American Airlines is preparing to launch its first retrofitted Boeing 777-300ER featuring newly designed, enclosed business-class suites. The debut is tied to American’s “Flagship First” product being phased out, with the new suites taking over on the aircraft coming into service.

The new configuration is set to operate on an initial international route, reported as New York–Buenos Aires. The aircraft includes 70 enclosed suites and offers free onboard Wi‑Fi. One outlet also says the broader retrofit effort involves a 20-plane program scheduled to be completed during 2027.

Across the coverage, the core points—first 777-300ER retrofit, enclosed suite layout, and rollout timing—are consistent. The main differences are in emphasis: one piece highlights the “last call” aspect for Flagship First, while the other focuses on when international first class ends and the planned expansion of the 777 retrofit program.
